Sangjin Lee updated YARN-4074:
------------------------------
Attachment: YARN-4074-YARN-2928.POC.002.patch
Posting a v.2 POC patch. This adds the flow run query.
As for [~djp]'s comments, yes, I agree that the reader code needs more serious
refactoring, both in the API as well as the implementation.
I believe [~varun_saxena]'s looking into cleaning up the filters, and so on in
YARN-3863. So improving the API would be taken up by Varun. Varun?
I'd also like to refactor the implementation more to restructure it. This POC
patch is by no means an indication of the final form of this patch. I just
wanted to get it out there so we can ensure it is correct and discuss the
approach taken here. I hope that clarifies things a bit.
